4. NAND Flash Right Media,Wrong Solution
Solid state
Low power consumption
Small size
Wrong Solution
Non-standard I/O interface
Not reliable - Requires error detection and correction (EDC/ECC)
Non XIP - No boot capabilities (Requires additional EEPROM/ROM/NOR)
Standards/API keep changing (block size, I/O, parameters)
1Gbit NAND has non-compatible geometry (2KB page size)
MLC NAND flash requires new hardware and software
